so, the light travels 1.08 X 10^12 m/h , 3.00 X 10^5 km/s and
8.33 X 10^7 km/h.
[ 3.00 X 10^8 * 3600 ; (there are 3600 seconds in an hour)
= 10800 X 10^8 m/s
= 1.08 X 10^12 m/h ]

Answer:
Step-by-step explanation:
<u>1) Find the radius</u>
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
where the two points are 
and 
Plug in the points (7,1) and (-1,-5)
Therefore, the radius of the circle is 10 units.
<u>2) Plug the data into the equation of a circle</u>
Equation of a circle (when not centred at the origin):
where the centre is 
and r is the radius
Plug in the centre (7,1) as (h,k)
Plug in the radius 10
I hope this helps!

Answer:
63 grams of protein.
Step-by-step explanation:
3 ounces = 21 grams of protein.
Question is how many grams are in 9 ounces, you then have to find the ratio that you need to use to find out how many grams of protein are in 9 ounces. Therefor you divide the amount that we don't know the equal amount of grams by the amount we do know the equal amount of grams, giving us the ratio.
9 divided by 3 = ratio (3)
Then use the ratio for the grams of protein.
21 x 3 = 63.
